CVE-2025-9860 is a stored cross-site scripting vulnerability in the natata7 Mixtape WordPress plugin affecting all versions up to and including 1.1. The issue stems from improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of user-supplied attributes in the 'mixtape' shortcode. This flaw allows authenticated users with contributor-level privileges or higher to inject malicious scripts that execute in the context of other users viewing the injected content. The CVSS 3.1 base score is 6.4 (medium), with network attack vector, low attack complexity, and privileges required at the contributor level. The vulnerability impacts confidentiality and integrity but not availability. No patch or official remediation has been disclosed as of the published date.

An attacker with contributor-level access can exploit this vulnerability to inject and store malicious scripts within pages using the 'mixtape' shortcode. These scripts execute in the browsers of users who view the infected pages, potentially leading to theft of sensitive information or session hijacking. The impact affects confidentiality and integrity but does not affect availability. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the Mixtape plugin if possible. Monitor vendor channels for updates regarding patches or official mitigations.
